WHAT is this life if, full of care,
We have no time to stand and stare?—
No time to stand beneath the boughs,
And stare as long as sheep and cows:
No time to see, when woods we pass,
Where squirrels hide their nuts in grass:
No time to see, in broad daylight,
Streams full of stars, like skies at night:
No time to turn at Beauty's glance,
And watch her feet, how they can dance:
No time to wait till her mouth can
Enrich that smile her eyes began?
A poor life this if, full of care,
We have no time to stand and stare.
By William Henry Davies
In Science, we have been learning all about Gravity. We know Sir Isaac Newton discovered the law of gravity and it is a force that pulls all objects towards the Earth.
'One day, while he was sitting under a tree, an apple fell off the tree and hit him on the head. He thought that there must be a reason why the apple fell off the tree. He worked out that something must be pulling the apple downwards and after much thinking he figured it was gravity that was pulling the apple down.'
Sir Isaac Newton
We found out all objects fall at the same rate, no matter what their mass is. All objects accelerate at the same time and speed because we dropped them at the same time. However, objects with a greater mass will fall quickly to the ground than objects which are lighter because their gravitational pull is stronger.
But, what happened when we dropped the two balls, which were the same size, but one had a much larger mass?
